- The disclosure relates to a camera assembly and an electronic device including the same.
- Optical information of a subject is input to an image sensor of a camera of a portable electronic device through a lens and is converted into an electrical signal. At this time, the horizontal/vertical sizes of an image are determined by an angle of view that is an optical design specification.
- To obtain information outside an angle of view, a user, after taking a first image, may rotate a mobile phone itself and may take a second image. When the user directly rotates the mobile phone and takes an image, an image in which the first image and the second image are matched may not be obtained due to temporal and spatial differences from the photo previously taken.
- An aspect of the disclosure is to provide a camera assembly capable of changing an angle of view. Furthermore, another aspect of the disclosure is to provide an electronic device that includes a rotating optical member including two rotational degrees of freedom, but minimizes an increase in thickness.

support ball 146 of theholder 140 may be disposed such that part of thesupport ball 146 is inserted into thesupport recess 1123 on theinclined surface 1122. Accordingly, rotation of theholder 140 and thereflective member 130 may be supported by thesupport recess 1123 and thesupport ball 146. - The
lens module 150 may be disposed behind theholder 140 and thereflective member 130. Thelens module 150 may include thelens housing 151 having the lens inside, thelens plate 152 on which thelens housing 151 is disposed, and theimage sensor 154 disposed behind thelens housing 151. - The
lens housing 151 may be coupled to thelens plate 152 so as to be movable relative to thelens plate 152. Thelens plate 152 may be connected with and fixed to thebase 112 of theframe 110.

The optical axis direction may refer to the forward or rearward direction in the drawings. - The
image sensor 154 and thesecond circuit board 156 may be coupled to thelens plate 152. Accordingly, theimage sensor 154 and thesecond circuit board 156 may be fixed, and only thelens housing 151 and thelens 153 may move in the optical axis direction. As thelens 153 moves relative to thelens plate 152, thecamera assembly 100 may be focused. - Referring to
FIG. 3B , a firstmovable member 120 a and a secondmovable member 120 b may be coupled to thefirst sidewall 114 a and thesecond sidewall 114 b, respectively. Themovable members 120 may be coupled so as to slide forward or rearward relative to thesidewalls 114. - In various embodiments, driving forces of the
movable members 120 may be formed by magnets and thecoils 1142. Referring toFIG. 3B , themetal plate 1144 and at least onecoil 1142 wound around themetal plate 1144 may be disposed in thefirst sidewall 114 a and thesecond sidewall 114 b. Furthermore, the magnets facing thecoils 1142 may be disposed on the firstmovable member 120 a and the secondmovable member 120 b. -

FIGS. 4 and 5 , theinclined surface 1122 may be formed on thebase 112. Theyoke 1124 may be disposed in thespace 1121 formed by theinclined surface 1122. Thefirst magnet 142 interacting with theyoke 1124 may be disposed on theholder 140. Thesupport recess 1123 in which thesupport ball 146 of theholder 140 is disposed may be formed on theinclined surface 1122. Theyoke 1124 may include a magnetic body. - In various embodiments, the

Thethird surface 136 of thereflective member 130 may be seated on theholder 140. For example, thefirst surface 132 may serve as a light entrance surface, thesecond surface 134 may serve as a light exit surface, and thethird surface 136 may serve as a reflective surface. Thefirst surface 132 and thesecond surface 134 of thereflective member 130 are not necessarily limited to being connected to be perpendicular to each other, and thefirst surface 132 and thesecond surface 134 may be connected at various angles. - In various embodiments, the
reflective member 130 may include a mirror. The mirror may change the optical path of the external light incident through theopening 1161 formed in an upper wall of thecover 116. For example, the external light may reach thereflective member 130 through theopening 1161 formed in the upper wall of thecover 116, and the light reflected by the mirror may reach thelens 153. - The
reflective member 130 may change the optical path of the external light to direct the external light toward thelens 153. For example, thereflective member 130 may include a reflective surface (e.g., thethird surface 136 ofFIG. 4 ). The reflective surface may be disposed to form a predetermined angle with the external light. The reflective surface may face theopening 1161 formed in the upper wall of thecover 116 and thelens 153 disposed in thecover 116. - In various embodiments, the
reflective member 130 may be implemented with only thethird surface 136 without including thefirst surface 132 and/or thesecond surface 134. For example, thereflective member 130 may include a mirror, and thethird surface 136 may include a reflective surface. - The first
movable member 120 a and the secondmovable member 120 b may be slidably coupled to thefirst sidewall 114 a and thesecond sidewall 114 b, respectively. Thefirst guide grooves 1143 for guiding movements of the firstmovable member 120 a and the secondmovable member 120 a may be formed on thefirst sidewall 114 a and thesecond sidewall 114 b. For example, the firstmovable member 120 a and the secondmovable member 120 b may be inserted into thefirst guide grooves 1143 and may move forward or rearward. - The first
movable member 120 a and the secondmovable member 120 b may be connected to connecting parts of theholder 140. Referring toFIG. 5 , connectingrecesses 145 may be formed on the connecting parts of theholder 140.Protrusions 124 protruding in a ball shape may be formed on front end portions of the firstmovable member 120 a and the secondmovable member 120 b. Theprotrusions 124 may be disposed such that parts thereof are inserted into the connecting recesses 145. - The first
movable member 120 a and the secondmovable member 120 b may further includeyokes 126 disposed in positions adjacent to theprotrusions 124, respectively. Attraction forces may act between theyokes 126 and thesecond magnets 144 of theholder 140. Thesecond magnets 144 may attract theholder 140 rearward when the firstmovable member 120 a and the secondmovable member 120 b move rearward. Theyokes 126 may include magnetic bodies. - The
support ball 146 of theholder 140 may be disposed such that part of thesupport ball 146 is inserted into thesupport recess 1123 on theinclined surface 1122. Accordingly, rotation of theholder 140 and thereflective member 130 may be supported by thesupport recess 1123 and thesupport ball 146. - In various embodiments, the
second magnets 144 and theyokes 126 may be omitted. For example, theholder 140 and themovable members 120 may be connected such that theholder 140 moves rearward together with themovable members 120 even in a case where the firstmovable member 120 a and the secondmovable member 120 b move rearward. In this case, theholder 140 may move together depending on displacements of themovable members 120, and therefore thesecond magnets 144 and theyokes 126 for pressing theholder 140 backward may be omitted. Themovable members 120, when moving forward, may press theholder 140 forward as described above. -
FIG. 6 is a view illustrating thelens module 150 of thecamera assembly 100 according to an embodiment. - The
lens module 150 may include thelens plate 152, thelens housing 151 disposed on thelens plate 152, the at least onelens 153 provided in thelens housing 151, and theimage sensor 154 disposed behind thelens housing 151. - At least one
opening 1523 into which acoil 1524 is inserted may be formed in thelens plate 152. Thecoil 1524 may be formed by being wound around ayoke 1526. Secondcorresponding guide grooves 1521 in which rollingmembers 155 are disposed may be formed on thelens plate 152.Second guide grooves 1513 corresponding to the secondcorresponding guide grooves 1521 may be formed on thelens housing 151. The rollingmembers 155 may be disposed between thesecond guide grooves 1513 and the secondcorresponding guide grooves 1521 and may decrease frictional forces generated when thelens housing 151 moves. - A
magnetic body 1522 corresponding to thecoil 1524 of thelens plate 152 may be disposed on thelens housing 151. Themagnetic body 1522 may be disposed on a lower surface of thelens housing 151 that faces thelens plate 152. - A magnetic field may be formed between the
lens housing 151 and thelens plate 152 by themagnetic body 1522 of thelens housing 151. In this case, when current flows through thecoil 1524 of thelens plate 152, a Lorentz force may act on thecoil 1524 of thelens plate 152. Because thelens plate 152 is connected and fixed to thebase 112, thelens housing 151 may move forward or rearward. - Sliding
grooves 1511 may be formed onside surfaces 1512 of thelens housing 151. As will be described below, at least parts of themovable members 120 may be inserted into the slidinggrooves 1511. Themovable members 120 and thelens housing 151 that move forward or rearward may be supported or guided by the slidinggrooves 1511. -
FIG. 7 is a view illustrating a coupling of thesidewalls 114, themovable members 120, thelens housing 151, and thelens plate 152 of thecamera assembly 100 according to an embodiment. - In an embodiment, the
camera assembly 100 may include a first linear actuator module for actuating the firstmovable member 120 a and a second linear actuator module for actuating the secondmovable member 120 b. - The first linear actuator module and the second linear actuator module may include the
coils 1142 formed in thesidewalls 114 and themagnetic bodies 122 formed on themovable members 120 facing thesidewalls 114. Thecoils 1142 may preferably be formed by being wound around yokes. - The
first guide grooves 1143 may be formed on thesidewalls 114. The firstcorresponding guide grooves 121 that correspond to thefirst guide grooves 1143 may be formed on themovable members 120. Thefirst guide grooves 1143 and the firstcorresponding guide grooves 121 may be disposed to face each other. The rollingmembers 125 may be disposed between thefirst guide grooves 1143 and the firstcorresponding guide grooves 121. The rollingmembers 125 may include balls. When themovable members 120 move forward or rearward relative to thesidewalls 114, frictional forces may be decreased by the rollingmembers 125. - The sliding
grooves 1511 may be formed on the side surfaces 1512 of thelens housing 151. At least parts of themovable members 120 may be inserted into the slidinggrooves 1511. Accordingly, movements of themovable members 120 that move forward or rearward may be additionally guided. - The
lens module 150 may include thelens plate 152 and thelens housing 151 disposed on thelens plate 152. Thesecond guide grooves 1513 may be formed on the lower surface of thelens housing 151. The secondcorresponding guide grooves 1521 may be formed on thelens plate 152. Likewise to thefirst guide grooves 1143 and the firstcorresponding guide grooves 121, thesecond guide grooves 1513 and the secondcorresponding guide grooves 1521 may be disposed to face each other. The rollingmembers 155 may be disposed between thesecond guide grooves 1513 and the secondcorresponding guide grooves 1521. Accordingly, thelens housing 151 may be movable forward or rearward relative to thelens plate 152. - The
magnetic bodies 122 formed on themovable members 120 may include N-pole areas facing thesidewalls 114 and S-pole areas facing thelens housing 151. Magnetic fields B facing toward thesidewalls 114 may be formed by the N-pole areas. At this time, Lorentz forces may act on thecoils 1142 through which currents flow in the magnetic fields. For example, when current flows through thecoil 1142 in the clockwise direction (when current flows upward in the drawing), a Lorentz force acting in the rearward direction may act on thecoil 1142 and thesidewall 114 in which thecoil 1142 is disposed. At this time, themovable member 120 slidably coupled to thesidewall 114 may move forward because thesidewall 114 is fixed to thebase 112. Accordingly, when current flows through thecoil 1142 in the counterclockwise direction, themovable member 120 may move in the opposite direction. - The
movable members 120 may include the firstmovable member 120 a and the secondmovable member 120 b, and thesidewalls 114 may include thefirst sidewall 114 a and thesecond sidewall 114 b. Currents may flow through thecoils 1142, which are included in thefirst sidewall 114 a and thesecond sidewall 114 b, in different directions, and the firstmovable member 120 a and the secondmovable member 120 b may move in different directions. - Meanwhile, as described above, the sliding
grooves 1511 may be formed on the side surfaces 1512 of thelens housing 151. At least parts of themovable members 120 may be inserted into the slidinggrooves 1511. Accordingly, movements of themovable members 120 and thelens housing 151 that move forward or rearward may be guided or supported by each other. -
FIG. 8 illustrates a front surface and a rear surface of an electronic device according to another embodiment. - The
electronic device 200 according to the other embodiment will be described with reference toFIG. 8 . Theelectronic device 200 according to the other embodiment may include a housing and a camera assembly provided in the housing. - The housing may include a
front surface 201 and arear surface 202, and openings may be formed in partial areas of thefront surface 201 and therear surface 202 of the housing. The camera assembly may be disposed in the housing. Adisplay area 203 may be formed on thefront surface 201. - The
camera assembly 100 may include at least some of the above-described components. The optical axis of the lens of thecamera assembly 100 may be formed between the front surface and the rear surface of the housing. The lens and the image sensor of the camera assembly may be disposed in the housing, and the holder and thereflective member 130 disposed in the optical axis direction of the lens may be disposed under the opening such that at least parts thereof are exposed through the opening. - External light may be incident on the reflective member through the opening formed in the front surface or the rear surface of the electronic device. The path of the external light may be changed by the reflective member. The reflective member may allow the external light to pass between the front surface and the rear surface of the housing and reach the lens.
- Based on
FIG. 8 , the first movable member and the second movable member may be actuated in the up/down direction, and the optical axis direction of the lens may also be formed in the up/down direction of the electronic device. - As described above, the reflective member and the holder may be rotated about the first axis of rotation and the second axis of rotation by movements of the first movable member and the second movable member. In this case, the first axis of rotation may be formed in a direction to pass through the front surface and the rear surface of the electronic device. The second axis of rotation may be formed in a direction to pass through opposite side surfaces disposed between the front surface and the rear surface of the electronic device. The first axis of rotation and the second axis of rotation may be perpendicular to each other, and both the first axis of rotation and the second axis of rotation may be perpendicular to the up/down direction of the electronic device.
- The
camera assembly 100 of theelectronic device 200 according to the other embodiment may have two or more rotational degrees of freedom and may thus have a wide angle of view. In this case, an increase in the thickness of the electronic device may be minimized by forming the optical axis of the lens module in the lengthwise direction (the vertical direction ofFIG. 8 ) or the widthwise direction (the horizontal direction ofFIG. 8 ) of the housing. -
FIGS. 9A and 9B are views illustrating rotations of the reflective member depending on movements of the first movable member and the second movable member in an embodiment.FIG. 9A illustrates a tilting operation, andFIG. 9B illustrates a panning operation.FIG. 10 is a block diagram of an electronic device according to another embodiment.FIG. 11 is a flowchart of the electronic device according to the other embodiment. - Hereinafter, in
FIGS. 9 to 11 , to define tilting and panning, the leftward direction of thecamera assembly 100 illustrated inFIG. 9A (the direction in which thereflective member 130 is located) is defined as the forward direction, and the rightward direction is defined as the rearward direction. - As illustrated in
FIG. 9A , a tilting operation may refer to an operation in which thereflective member 130 rotates upward and downward with respect to the front of thecamera assembly 100. During the tilting operation, thereflective member 130 may rotate about the first axis of rotation (an axis A). The first axis of rotation may be formed inside a support ball (e.g., thesupport ball 146 ofFIG. 3A ) that supports the rotation of thereflective member 130, or may be formed adjacent to the support ball. - As illustrated in
FIG. 9B , a panning operation may refer to an operation in which thereflective member 130 rotates leftward and rightward with respect to the front of thecamera assembly 100. During the panning operation, thereflective member 130 may rotate about the second axis of rotation (an axis B). The second axis of rotation may be formed inside the support ball (e.g., thesupport ball 146 ofFIG. 3A ) that supports the rotation of thereflective member 130, or may be formed adjacent to the support ball. - Tilting and panning may be differently defined depending on a direction in which the
camera assembly 100 is disposed. Thecamera assembly 100 according to an embodiment of the disclosure may have at least two rotational degrees of freedom and is not limited by a term, such as panning, tilting, or swiveling, which refers to a rotational direction. - Referring to
FIG. 9A , when the firstmovable member 120 a and the secondmovable member 120 b move in the same direction, thereflective member 130 may rotate about the first axis of rotation (e.g., the axis A). As described above, each axis of rotation may be formed in the center of thesupport ball 146, and each rotation may be supported by thesupport ball 146. - Referring to
FIG. 9B , when the firstmovable member 120 a and the secondmovable member 120 b move in different directions, thereflective member 130 may rotate about the second axis of rotation (e.g., the axis B). - The first
movable member 120 a and the secondmovable member 120 b may be independently actuated depending on directions of currents flowing through therespective coils 1142. Accordingly, thereflective member 130 may be disposed at various angles depending on displacements of themovable members 120. - In various embodiments, when the
movable members 120 move forward, theprotrusions 124 on the front end portions of themovable members 120 may be inserted into the connectingrecesses 145 of theholder 140 and may move theholder 140 forward. In contrast, when themovable members 120 move rearward, theprotrusions 124 of themovable members 120 may be separated from the connecting recesses 145. Theholder 140 may be moved rearward by pre-load parts when themovable members 120 move rearward as described above. That is, the pre-load parts (e.g., thesecond magnets 144 of theholder 140 and theyokes 126 of the movable members 120) may be configured to press theholder 140 rearward. - Referring to
FIG. 10 , in the other embodiment, the electronic device 1000 (e.g., theelectronic device 200 ofFIG. 8 ) may include aprocessor 1010 andcontrol circuitry 1020 for controlling anactuator module 1030 of a camera assembly (e.g., thecamera assembly 100 ofFIGS. 9A and 9B ). - The
actuator module 1030 may include afirst actuator 1031 and asecond actuator 1032. As described above, thefirst actuator 1031 and thesecond actuator 1032 may linearly move in an optical axis direction (a forward or rearward direction) of a lens (e.g., thelens module 150 ofFIG. 1 ) relative to sidewalls (e.g., thesidewalls 114 ofFIG. 2 ) of the camera assembly (e.g., thecamera assembly 100 ofFIGS. 9A and 9B ). - The first actuator (e.g., the first
movable member 120 a ofFIGS. 9A and 9B ) and the second actuator 132 (e.g., the secondmovable member 120 b ofFIGS. 9A and 9B ) may be connected with a reflective member (e.g., thereflective member 130 ofFIGS. 9A and 9B ) or a holder in which thereflective member 130 is disposed and may rotate the reflective member about a first axis of rotation (e.g., the axis A ofFIG. 9A ) or a second axis of rotation (e.g., the axis B ofFIG. 9B ). - The
control circuitry 1020 may independently drive thefirst actuator 1031 and thesecond actuator 1032. For example, thecontrol circuitry 1020 may control thefirst actuator 1031 to move forward or rearward and may simultaneously or sequentially control thesecond actuator 1032 to move forward or rearward. - In various embodiments, the
control circuitry 1020 may be included as a component of the camera assembly. Alternatively, thecontrol circuitry 1020 may be integrated with the camera assembly. For example, a first circuit board (e.g., thefirst circuit board 128 ofFIG. 1 ) may be disposed outside thefirst actuator 1031 and/or thesecond actuator 1032. - The
electronic device 1000 may further include theprocessor 1010. Theprocessor 1010 may be electrically connected with thecontrol circuitry 1020 and may transmit instructions associated with driving thefirst actuator 1031 and thesecond actuator 1032 to thecontrol circuitry 1020. - For example, when a user who uses the
electronic device 1000 performs an operation of adjusting an angle of view of a camera (e.g., thecamera assembly 100 ofFIGS. 9A and 9B ), theprocessor 1010 may transmit an operation request corresponding to the user's instruction to thecontrol circuitry 1020. - In various embodiments, the operation request from the
processor 1010 may include a first rotation angle of the reflective member (e.g., thereflective member 130 ofFIGS. 9A and 9B ) about the first axis of rotation (e.g., the axis A ofFIG. 9A ) and a second rotation angle of the reflective member about the second axis of rotation (e.g., the axis B ofFIG. 9B ). In this case, theprocessor 1010 may calculate the rotation angles of thereflective member 130, based on the user's instruction and may transmit the calculated rotation angles to thecontrol circuitry 1020. In this case, thecontrol circuitry 1020 may compute directions and distances where thefirst actuator 1031 and thesecond actuator 1032 are to move, based on the requested first rotation angle and the requested second rotation angle of thereflective member 130 and may drive thefirst actuator 1031 and thesecond actuator 1032 depending on the directions and the distances. - In various embodiments, the operation request from the
processor 1010 may include directions and distances where thefirst actuator 1031 and thesecond actuator 1032 are to move. In this case, theprocessor 1010 may compute the first rotation angle and the second rotation angle that correspond to a user operation, may compute directions and distances where thefirst actuator 1031 and thesecond actuator 1032 are to move, based on the first rotation angle and the second rotation angle, and may transmit the directions and distances to thecontrol circuitry 1020. Thecontrol circuitry 1020 may drive thefirst actuator 1031 and thesecond actuator 1032 depending on the computed directions and distances. - Referring to
FIG. 11 , thecontrol circuitry 1020 may receive an operation request from theprocessor 1010 and may drive thefirst actuator 1031 and thesecond actuator 1032 forward or rearward. - The operation illustrated in
FIG. 11 may be an example of a case in which only a tilting operation is performed or only a panning operation is performed, and the camera assembly according to various embodiments may simultaneously perform a tilting operation and a panning operation. - First, the
control circuitry 1020 may determine whether the operation request from theprocessor 1010 corresponds to a panning operation or a tilting operation. In a case where the operation request from theprocessor 1010 corresponds to the tilting operation, thecontrol circuitry 1020 may control thefirst actuator 1031 and thesecond actuator 1032 such that thefirst actuator 1031 and thesecond actuator 1032 move the same distance in the same direction. In a case where the operation request from theprocessor 1010 corresponds to the panning operation, thecontrol circuitry 1020 may control thefirst actuator 1031 and thesecond actuator 1032 such that thefirst actuator 1031 and thesecond actuator 1032 move the same distance in different directions. - i) A Case where the
First Actuator 1031 and theSecond Actuator 1032 Move the Same Distance in the Same Direction (e.g.,FIG. 9A ) - That is, this case may correspond to a case where the relative displacement between the
first actuator 1031 and thesecond actuator 1032 is zero, and the reflective member (e.g., thereflective member 130 ofFIG. 9A ) may perform only a tilting operation. For example, in a case where both the first actuator 1031 (e.g., the firstmovable member 120 a ofFIG. 9A ) and the second actuator 1032 (e.g., the secondmovable member 120 b ofFIG. 9A ) move the same distance forward, thereflective member 130 may rotate about the first axis of rotation (e.g., the axis A ofFIG. 9A ) in the clockwise direction. For example, in a case where both the first actuator 1031 (e.g., the firstmovable member 120 a ofFIG. 9A ) and the second actuator 1032 (e.g., the secondmovable member 120 b ofFIG. 9A ) move the same distance rearward, thereflective member 130 may rotate about the first axis of rotation (e.g., the axis A ofFIG. 9A ) in the counterclockwise direction. - ii) A Case where the
First Actuator 1031 and theSecond Actuator 1032 Move the Same Distance in Different Directions (e.g.,FIG. 9B ) - The reflective member (e.g., the
reflective member 130 ofFIG. 9A ) may perform only a panning operation. For example, in a case where the first actuator 1031 (e.g., the firstmovable member 120 a ofFIG. 9B ) moves forward and the second actuator 1032 (e.g., the secondmovable member 120 b ofFIG. 9B ) moves the same distance rearward, the reflective member may rotate about the second axis of rotation (e.g., the axis B ofFIG. 9B ) in the counterclockwise direction (when the reflective member is viewed from above). For example, in a case where the first actuator 1031 (e.g., the firstmovable member 120 a ofFIG. 9B ) moves rearward and the second actuator 1032 (e.g., the secondmovable member 120 b ofFIG. 9B ) moves the same distance forward, the reflective member may rotate about the second axis of rotation (e.g., the axis B ofFIG. 9B ) in the clockwise direction (when the reflective member is viewed from above). - iii) A Case where the
First Actuator 1031 and theSecond Actuator 1032 Move Different Distances - The
reflective member 130 may simultaneously perform a tilting operation and a panning operation. For example, in a case where thefirst actuator 1031 and thesecond actuator 1032 move forward, but thefirst actuator 1031 moves further forward than thesecond actuator 1032, thereflective member 130 may perform a tilting operation to rotate about the axis A in the clockwise direction and may perform a panning operation to rotate about the axis B in the counterclockwise direction. -
